The present invention'is an improvement on the general construction ofcarving-machine described in United States Letters Patent granted to meunder date of November 17, 1896, No. 571,535, and, like it, has for itsobjects to develop a maximum amount of chiciency, to insure a ready andeasy manipulation of the tool-spindles, to insure the development ofhigh speeds for the spindles, to reduce friction to a minimum, and toinsure diversity of adjustment among the several parts. In addition tothese, however, the objects of the present device are to reduce theactual number of shafts by which the tool-belts are driven; to providespecialdevices for tightfor driving or rotating the stock operated onfrom the main shaft by which the tool-belts are driven; to provide meansfor disengaging 'such driving mechanism at the will of the operator; toprovide means whereby during the swinging of the frame the tools may bemoved parallel to themselvesthat is to say, may preserve a constantangle with the plane of the stock frame; to provide certain reversecutting attachments whereby the pattern of any stock operated on may bethe reverse counterpart of a pattern previously or subsequently turnedout by the machine; to provide special means for mounting the severaltool-casings; to provideaspecial construction of tool-spindle,especially in the particular of mounting the spindle-pulley; to providea special construction of tool-chuck; to provide means whereby the toolsofeach pair shall simultaneously rotate in opposite directions; toprovide a special arrangement of guidepulleys for the tool-belts toeffect such reverse rotation, and to provide further and other detailsmore apparent from a detailed description of the construction, which isas follows:

Referring to the drawings, 1 and 2 represent, respectively, the upperand lower supporting-brackets, between which the inner vertical frame 3of the machine is swung. Pivotally mounted between the free ends of theupper and lower members of the frame 3 is the angular post 4, said postconstituting the pivot about which the outer frame of the machinerevolves. This outer frame (or extension) comprises the post 4,alreadyreferred to, the series of vertically-oscillating arms 5, pivotallyembracing the post 4 at approximately their medial portions, the rearconnecting post 6, the front tool supporting beam 7, and theconnecting-rod 8. The rearward extensions of the arms 5 are curved awayfrom the stock-frame in order to allow for a full and uninterruptedoscillation of the frame in a horizontal plane in front of thestock-frame. Like in my patented construction already referred to, thetool-supporting beam in the present case is pivotally secured to thefront ends of the arms 5 by means of blocks or pieces 9, pivotallymounted between the ends of the arms of a U-shapedbracket, the forkedends of the arms 5 pivotally embracing each block.

In the particulars already described the present device does not varymaterially from the patented machine referred to, except in the additionof the rearward extensions to the arms 5, by which the latter and thetools supported by them are held rigid and better balanced. In thepresent machine, however, I have provided means whereby the spindles ofthe tool-casings are driven direct from the main drive-shaft, therebydispensing with the necessity of mounting a supplemental shaft in thepost- 4, as was done in the old machine. The main drive-shaft 11 isconcentric with the axis of oscillation of theinner frame 3, the lowerend of the shaft being supported on an independent bracket 12,pr0jectingfrom the beam or wall carrying the machine; and the u per end of theshaft passing through th bracket 1 and through the upper pivot of thesaid frame 3. The shaft is driven from any suitable source of power (notshown) and has disposed thereon beltpulleys 13, corresponding in numberto the number'of tools carried by the beam 7, each pulley being providedwith a juxtaposed curved belt fork or guard 14, secured in positionalong the supporting beam or wall of the machine, above and below theperipheral edges of the pulley and extending beyond the same, wherebythe slipping of the drive belts 15 off the pulleys is prevented; One lapof each tool-driving belt 15, after passing through abelt-tightener, tobe specifically described, passes over one of the guide-pulleys16,1nounted on a bracket 17,pivotally secu red along the inner surfaceof. the outer 'wall of the post 4, (it being remembered that the post 4has two walls, being virtually an angle-bar, as best seen in Fig. 6,)thence along one of the pulleys of the pulley-block 18, mounted betweenthe arms of the yoke 19, embracing the tool-casing, and thence over thepulley 20, carried by the tool-spindle. The opposite lap of the beltafter leaving the pulley passes along the remaining pulley mounted inthe pulley-block 18, and thence over the remaining guidepulley 16,mounted on the opposite side of the bracket 17, whence it passes back tothe main drive-pulley 13, the lapsof the belt embracing the inner andouter pillars 3' 3", respectively, of the frame 3; That the bracket 17,carrying the pulleys 16 16, may conform to the various angles to whichthe arm 5 of the outer frame may be dipped in their vertical sweep alongthe stock operated on, the said bracket is provided with a for- 'wardextension or arm 17, the free end of which is pivotally secured totherod 8, by which the series of arms is connected.

The belt-tighteners (shown in relative position in the plan view, Fig.10, and illustrated -in detail in Figs. 8 and 9) are mounted on acylindrical rod 21, disposed parallel to the pillar 3 and securedthereto by arms 22. Each tightener is composed of a split tubularporjtion 23, revolubly mounted and loosely passed over the rod andsupported by the hub or col- .lar 24 of the ratchet 25, slipped over andscrewed to the rod. Extending diametrically from the tube 23 are arms25, between the free ends of which are mounted the pulleys 526, one ofthe lower arms being provided with ia depending lug 27, to which issecured one fend of a spring 28, coiled about the hub 24 land havingitsopposite or free end so arranged .as to engage the teeth of theratchet-disk 25. The posit-ion of the belt as it passes over theIpulleys 26 is shown in Fig. 9, and it is apparent that by running. thefree end of the .spring along the teeth of the ratchet-disk the .springwill be wound up, causing the pulleys IIO to exert pressure against thebelt in the direction shown by the arrows in Fig. 9. be remarked, inpassing, that while the machine is in motion a maximum tension isexerted on that lap of the belt coming directly from the toolspindlestoward the main drivepulley, and hence a maximum amount of slack will beimparted to the lap to which the tightener is applied. When the machineis at rest, the slack on both laps Will be equalized, this resulting ina tightening or shortening of the slack side and rocking thetightener-arms and pulleys carried by them more nearly in line with thebelt, or approximately as shown by dotted lines in Fig. 9. Thus thepresent tightener yields and conforms to the degree of tension inherentin the lap passing through it. In order to prevent the tightening-armsfrom swinging too far under the tightening action of the belt as themachine is being stopped, Iprovide each tightener with a limiting-arm29, against which the head of the spindle 30 of the nearest pulleystrikes. Were it not for the limitingarm 29 the chances are that as thebelt stretched from prolonged use the arms of the tightener would havetoo much play between their extreme positions as the machine wasalternately stopped and started and the belt would have a tendency toslip off the pulleys while the latter were thus shifting from oneextreme to the other. Of course when the belt becomes too long for theslack to be taken up by the tightener it is removed from the machine andaccordingly shortened.

As stated above, each bracket 17 is pivoted to oscillate in a verticalplane along the inner surface of the outer wall of the post 4. Thepivotal pin 30 (see Fig. 6) of the bracket passes through a cup 31,secured to the post, within which cup the seat of the bracket operates,said seat being provided with a wearing-plate 32, hearing against theantifrictionrollers 33, which in turn bear against a secondwearing-plate 34, located between the.

cup and post, the base of the cup being provided with a curved slot 35for the reception and guidance of the rollers. The pulleys are protectedand the belt is guided in a measure by the housings 36 37, respectively,the inner end of the bracket being further provided with a deflectedwall 38 to guide the lap of the belt as it approaches the nearestpulley. Upon an inspection of Figs. 1 and 2 it will be seen thatwitheach alternate bracket 17 each pulley is disposed on the oppositeside to that along which it is disposed on the adjacent or nearestbracket-that is to say, the disposition of the pulleys is just thereverse of that on the adjacent bracket. The reason of this is that thelap which leaves the forward pulley on one bracket must first pass overthe pulley mounted on the tool-spindle, while in the next bracketthe lapwhich leaves the forward pulley must pass under the pulley of thecorresponding tool-spindle, thereby imparting to each tool-spindle arotation which It may is opposite to that of its neighbor. The obj ectof this arrangement is that if all the tools rotated simultaneously inthe same direction the velocity at which they must revolve would have atendency, as their cutting ends came in contact with the stock, to forcethe end of the frame carrying the tools away from the work, whereas byimparting a contrary rotation to each succeeding tool this tendency tothus force the tools away from the work is overcome.

Like in my patent above referred to the rear ends of the spindle-casingsare pivotally connected to a connecting-bar 39 to enable the operator totilt all the tools simultaneously, the upper end of the bar in thepresent casing being connected to the lower end of a cord 40, passingover a guide-shoe 41, carried at the end of a weighted lever 42,pivot-ally mounted at the upper end of a staif or bar 43, pivotallyconnected to the two upper.

vertically-sweeping arms 5 at points forward or in advance of theconnecting-rod S, by

which the series of arms are united. The bal-.

ance-lever 42 of course enables the operator to tilt the series of toolswithout undue exersurface with a medial ridge 46, against each side ofwhich are adapted to bear the antifriction-rollers 47, held in place onthe one side by a nut 48, screwed over the screwthreaded lateral reducedextension or boss 49 of the pocket 50 of the tool-casing, and on theopposite side by the base of the pocket thus drawn firmly against therollers by the action of the nut. The parts are additionally secured bya bolt 51, driven through the opening of the nut into theinterior-screw-threaded portion of the boss 49. The yoke 19, which spansthe tool-casing on either side of the pocket and between the ends ofwhose arms.

terposed between the base of the pocket andv the inner end of the ring45. The lugs 57 limit the tilting of the yoke about the toolcasing.

The tool-casing and spindle and the manner of attaching the cutting-toolare also improved over the construction shown in the patent. In thepresent device the spindle is provided with a split band 58, which isinserted into the hollow of the pulley 20, the base of the groove of thelatter being pro vided with openings for the reception of thebinding-screws 59, which as they are driven against the band force thelatter against the tool-spindle, and thus hold the pulleysecurely inplace. To prevent the spindle (which is conical) from binding, a resultwhich might follow if the oil-cup were driven too forcibly against it, Iprovide the forward end of the pulley 20 with an annular shoulder 61,which bears against a seat 62, carried by the casing. The forward end ofthe tool-spindle is provided with a socket for the reception of theshank 63 of the cutting-tool, the latter being gripped bya chuck of thefollowing construction: The terminal expanded exteriorlyscrew-threadedhead 64 of the spindle is provided with an inner tapering oroutwardlyflaring mouth. Embracing the shank is a split ring 65, taperingtoward its opposite ends. Over the ring is adapted to be passed a nut66, whose inner surface conforms to the contour of the ring, and as thenut is driven home along the outer screw-threaded surface of the head 64it will cause the bevel end of the ring to follow along the bevel wallsof the mouth of the said head, thus causing the ring to close tightlyagainst the shank of the tool. (See Figs. 16 and 17.) In screwing on thenut 66 it is desirable that while the'tool-casing is being held with onehand and the nut driven with the other the spindle remain stationary.This I accomplish by forming two longitudinal grooves 67 along the outerperipheral surface of the spindle, either groove being adapted toreceive the inner end of a pin 68, mounted in the casing-wall, and whilethe machine is in operation held out of engagement with the groove by aresilient spring-wire 69, having its opposite ends secured between thelugs 70, disposed along the casing, and its medial portion engaging thelower of two transverse notches 71, cut in the shank of the pin. When itis desired to engage the pin with the base of the groove, the wire isallowed to snap into the outer notch, whereupon any movement of thespindle is prevented. (See Figs. 16 and 22.) This device is a veryeffective one for holding the spindle stationary while the tool is beinginserted into the spindle;

Under ordinary circumstances as the frame carrying the tool is swung infront of the stock-frame and the stock carried thereby (that is to say,swung in a horizontal plane) it is obvious that as both the inner andouter frames are swung about fixed centers the tools themselves willdescribe the path of an arc of a circle. In certain classes of work,however, especially flat work, it is desirable while the tool is beingadvanced in a horizontal plane along the work by the swinging of theinner frame that the tool shall move laterally along the stock-frame andat an angle therewith, to which the axis of rotation of the tool isinitially set. This is accomplished by the following tool-constrainingmechanism: Forming an upper extension of the tool-supporting beam is acylindrical rod 72, about which is passed a tubular sleeve 73, having anexpanded cylindrical base 74, the latter having cut-away portions orsegments, into which are received the depending fingers or extensions ofan outer sleeve 76, the walls of the outer sleeve being of a thicknessequal to that of the base 74, so that when the two sleeves are coupledthey form practically one cylinder. (See Fig. 12.) They in factconstitute a clutch the inner member of which is frictionally andrigidly held against the top of the tool-supporting beam by a nut 77,passed over the outer screw-threaded end of the rod and forced againstthe top of the inner sleeve. Pivotally embracing the walls of the outerdetachable sleeve is the outer forked end of a connecting-rod 78, whoseopposite or inner forked end embraces a collar 79, loosely mounted on aprojecting stud 80, forming a part of a sleeve 81, adapted to slide backand forth along a bar 82, horizontally disposed in front of thestock-frame and held in place by the terminal brackets 83, carried bysaid frame, the sleeve being split along its periphery to readily passby the bracket. (See Fig. 14.) Of course inasmuch as the connectionbetween the tool-supporting beam 7 and the series of arms 5 is a pivotalone, (asin the patented construction,) the toolsupporting beam beingsusceptible of independent oscillation in a horizontal plane, it isapparent that while the arms 5 or the frame of which they constitute themain part may swing in the arc of a circle the tools may be constrainedto move in parallel lines-that is, parallel to the direction in whichthe tool is originally set. In Fig. 11 I show the tool set originally atright angles to the stock-frame,

and when the outer frame has been shifted said figure the constrainingmechanism above referred to will compel the tool to move parallel toitself. That the tool shall moveparallel to itself is important withcertain classes of work, especially flat work. The special pivotalconnections of the opposite ends of the connecting-rod enable the latterto conform to any vertical sweep of the arms 5. For the sake ofillustration I have shown the tool as being constrained to move in linesperpendicular to the stock-frame; but it is apparent that this angle canbe initially changed by tilting the tool-supporting beam and the sleeve73 sufiiciently to cause the clutch mechanism to couple at any otherangle, and when once coupled to the connecting-rod the toolsupportingbeam must remain at the angle to which it and the tools carried therebyhave been set. When the cbnstraining mechanism is not intended to beused, the outer sleeve is simply uncoupled and the end of the connectandswung to the dotted position shown in ing-rod carrying the same issuspended to some convenient and stationary port ion of the frame. Thetools are then again free to describe any angles which the operator maygive them during the swinging of the frame. It maybe stated in passingthat mere friction will retain the clutches or sleeves in their coupledposition after once being united in the manner indicated, whatever bethe degree to which the arms of the outer frame maybe tilted in avertical plane.

In the machine so far described the tracer 84 is secured directly to thetool-supporting beam, asin my patented construction referred to, so thatwhatever movement is imparted to the tracer will be imparted to theseries of tools, and whatever maybe the pattern traced by the tracerwill be faithfully and exactly reproduced by the tools. It becomesdesirable, however, under certain circumstances to produce carvingswhich shall be the reverse counterparts of the pattern traced by thetracer-for example, in ornamental scrollwork, where one piece ofornament faces a similar pieceas, for instance, two heads or the like.For work of this kind it is essential that the tracer shall pass overthe pattern in a direction directly contrary to that which the toolsassume. For this purpose I provide the present machine withwhatlshalldenominate as the reverse-cutting attachment. Temporarilybolted or otherwise secured to the second arm 5 from the top of theframe and along the front of the same is a rocking segment 85, whosecurved rocking face is adapted to cooperate with a corresponding curvedface of a rocker-arm 86, temporarily pivoted at the bearing 86 on thepost 4 immediately below the arm 5, carrying the segment 85, the rockingfaces being united by two straps or cords 87, one end of each strapbeing connected to one end of one rocker-face and the opposite end tothe opposite end of the opposite rocker-face, the rocking surfaces underthe circumstances acting as two gearwheels, but superior to the latterin that they are much more sensitive, there being no loss of play underthe present constructions When the reverse-cutting attachment isemployed, the regular tracer 84 is removed and a suitable tracer 88employed. (See Fig. 5.) The body portion of this tracer is connected bya ball-and-socket joint 89 to the free end of the rocker-arm 86, theforward face of the tracer-body being grooved, so as to loosely embracethe rear face and beveled sides of a plate 90, temporarily securedwithin the hollow of the toolsupporting beam, (it being understood thatthe cross-section of the toolsupporting beam is substantially troughshaped, as seen in the drawings) along which the tracer is guided duringthe vertical sweep or swing of the rocker-arm. It will be apparent thatas the rocker-arm 86 is depressed or rocked downward the segment 85 andarm to which it is secured, and hence all the arms 5 of the frame, willrock upward, and when the rocker-arm is rocked upward the arms 5, and

hence the tools carried by them, will rock downward. It thereforefollows that for any pattern that may be traced by the tracer 88 thereverse counterpart will be carved by the series of tools. When it isdesirable to disconl inue the reverse cutting, the rocking segment androcker-arm and tracer are detached and the original tracer is restored.

In the majority of cases the stock operated on is held stationary to thestock-frame during the carving operation; but in many instances it isdesirable to rotate the stock, especially for such work as ornamentalposts and the like. For such cases I make provision to rotate the stockfrom power imparted from the main drive-shaftand by mechanism which isas follows: Mounted in a bearing 91 at the base of the machine andguided within a second bearing 92, projecting'from themainshal'tsupporting bracket 12, is a vertical counter-shaft 93, carrying atits upper end a cone-pulley 94, to which motion may be imparted by abelt (not shown) from the conepulley 95, (of which only the upperportion is visible in the drawing, Fig. 2,) carried by the main shaft.ter-shaft is provided with a horizontally-disposed pulley 96, from whichleads a belt 97 to a vertically-disposed pulley 98, mounted at the endof a bracket or arm 98, pivotally secured to the lowerhorizontalstock-frame guide-bar 99. The drop-shaft 100 of the pulley 98extends forward along and parallel to the base of the stock-frame, theforward end thereof being provided with a bevelpinion 101, normallymeshing with a bevelplate or driving disk 102, carried at the lowerend'of a vertical worm-shaft 103, which passes through a series ofbearing-webs 104:, forming the reinforcing-webs of the walls of avertical angle-bar bracket 105, serving as a support for said shaft, thesaid angle-bar bracket being bolted to the stock-frame 106. Distributedalong the shaft 103 are a series of worm-pinious 107, which mesh with acorresponding series of worm-wheels 108 at the outer ends of therotatable stock-holdin g spindles 109, mounted in the projecting wall ofthe angle-bar bracket 105. Correspondingly secured to the stock-frame isa second anglebar bracket 105, provided with a series of dead-spindles110 for retaining the opposite ends ofthe rotatable stock 111.

It has been stated that the pulley 98 was mounted at the end of abracket 98, pivotally secnred to the lower stock-frame guidebar 99. Thisconstruction is necessary to enable the operator at will to engage thepinion 101, carried at the forward end of the shaft 100, with ordisengage it from the driving-disk 102, accordingas he desires to impartmotion to the stock 111 or to stop the same. The mechanism by which thisengagementor disengagement is accomplished is as follows; Embracingloosely the shaft 100 at a point in advance of the pinion 101 is asleeve The lower end of the coun- 112, carried at the free end of thelong arm of a lever 113, pivoted to a depending jaw of the bracket 114at the base of the angle-bar bracket 105, so that virtually the forwardor free end of the drive-shaft 100 is suspended from the long artn ofthe lever 113, and the pinion 101 carried thereby is kept in engagementwith the driving-disk 102 by keeping the end of the long arm carryingthe sleeve raised sufficiently to effect such engagement. Thisisaccomplished by the tripping-lever 115, pivoted vertically to the sideof the bracket 114, the lower end of the lever being provided with a toe116, having a horizontal base and inclined sides, (and being, in efiect,a cam with sharp angles.) When the tripping-lever is in a verticalposition, the base of the toe squarely engages the upper surface of theshort arm of the lever 113, thus holding or forcing the long arm upwardand forcing the pinion 101 into engagement with the driving-disk 102.When the lever is tripped so as to disengage the base of the too fromthe lever 113 and to a position substantially as indicated by thedottedposition in Fig. 24, the short artn of the lever 113 will rise (underthe weight carried by the long arm) and the long arm will drop, thusdisengaging the pinion from the disk 102 and stopping the rotation ofthe stock 1 11. In order to stop the rotation of the disk 102 suddenlyupon thedisengagement therefrom of the pinion 101,1 secure to thetripping-lever a lateral arm or extension 117, having a terminal curvedbrake-shoe 118, which when the tripping-lever is tilted to itsdisengaging position will cause the brake-surface of the shoe to engagethe under surface of the disk 102 and serve as a brake therefor. Inorder to prevent straining of the disk 102 by the forcing of the pinion101 into engagement therewith, I secure to the base of the bottombearing of the worm shaft 103 a bracket 119, having a curved dependingarm which bears against the base of a circular groove 120, formed on theupper face of the disk 102, the arm serving to prevent any straining ofthe disk when the pinion 101 is forced into engagement therewith, andfreely working in the groove 120 when the disk is in motion. 1

Like in my patented machine above referred to,the stock-tram e as awhole is removable and adjustable to and from the tool-supporting frame.In the present device the stock-frame is removably mounted between thelower guide-bar 99 and the upper guide-bar 121, the lower guide-barbeing an angle-bar in crosssection, the upper surface of its horizontalmember supporting the bottom timber 122 of the stock-frame, whichtravels along said member on rollers 123. The upper guide-bar isprovided with a suitable tongue 124, entering a corresponding groove124, formed at the upper end of the stock-frame, so that the entirestock-frame can be removed from or inserted into position between theguide-bars. The latter are adjustable to and from the embrace the sidesof the walls of the boxings 126 126. Cast along the under surface of thehorizontal tnemberof the guide-bar 99 and located between the dependingwalls 129 is a lug 130, through which passes an adjusting screw or bolt.131, having bearings at each end of the pocket or boxing 126, (126,) theinner end of each bolt terminating in a supportingstud 132 and the outerwith an extension 131', carrying a sprocket-wheel 133, one of saidextensions being provided with a hand-wheel 134. The sprocket-chainpasses oversuitable sprocket-wheels 135, mounted along the outside andat the upper end of the vertical timbers l36,trom which projectrearwardly similar boxings 126", having adjusting-screws similar to thescrews 131, but not shown in the drawings. By thus turning the handwheel134 in one direction or the other the sprocket-chain will impartsimultaneous rotation to all the adjusting-screws, causing the upper andlower guide-bars, between which the stock-frame is mounted, to traveltoward or from the swinging frame at the pleasure of the operator. It isto be understood, of course, that the screws confined in the boxings126" pass through lugs corresponding to the lugs 130 of the lowerguide-bar 99.

In order to hold the stock-frame rigidly in place between the upper andlower guide-bars when once properly adjusted to any desirable position,I employ the following clamping mechanism: Pivoted approximately alongthe middle of the length of the lower guide-bar 99 and to a frontvertical depending bracket or arm 137 of the same is a foot-lever 138,the pivotal pin 139 thereof and the pins 140, disposed on each sidethereof and projecting from said arm, being of suflicient length tosupport a clamping-plate 141, (see Fig. 28,) having a slight rockingmotion on said pins, the foot-lever being interposed between saidclamping-plate and bracket. The short arm of the lever or that portionextending above the pivotal pin 139 terminates in a curved wedge 142,whose inclined wall cooperate with a similarly-inclined surface 142,formed on the adjacent wall of the clamping-plate, and carried by thefoot-lever at a suitable distance below the pivotal pin is a secondcurved wedge-shaped formation 143, coopcrating with a wedge-shapedcurved bearing-surface 144, formed at the base of the clamping-plate. Ifthe foot-lever is tilted in a direction as seen by the arrow in Fig. 28that is, so as to cause the surface 143 to IIO wedge against the surface144-the wedge 142 will be releasedfrom the surface 142, thus permittingthe clamping-plate to rock, so as to force the upper edge thereof firmlyagainst the timber 122 and hold the latter firmly against the adjacentwall of the guide-bar 99. On the other hand, should the foot-lever betilted in the opposite direction the wedge 142 will force itself againstthe surface 142 and wedge 143 will slide off or down the wedge 144, thusrocking the clamping edge of the plate 141 away from the timber 122,loo-sening the latter from the guide-bar and permitting the stock-frameto be shifted along the bar to any other position or to be entirelyremoved. The limits to which the foot-lever may be oscillated areindicated by its full and dotted positions in Fig. 27.

It was stated above that the axis of oscillation of the inner frame wasconcentric with the axis of rotation of the main drive-shaft 11. Thelatter has an independent lower hearing or support 12; but the upperportion passes through the upper pivot of the frame. That the shaftmaybe free from strain on the part of the swinging frame, 1 constructthe upper pivot or bearing for said inner frame follows: Theinnerpivotal end of the upper .member of said inner frame embraces the medialperipherally grooved conical portion of a tube 145, the grooves servingto retain antifriction rollers or balls 146, about which the frame canswing with the least amount of friction. The lower screw-threadedportion of the tube 145 is mounted in the lower section 147 of the upperbracket or hearing 1, screw-threaded on the interior, whereby the tubeand rollers 146, carried by it, can always be screwed upward and firmlyagainst the walls of the conical opening formed in the pivotal end ofthe upper member of the swinging frame. The uppersmooth portion of thetube passes through the middle section 148 of the bracket 1, and theupper projecting end of the shaft 11, which passes loosely through thetube, is carried or guided by the upper section 149 of the bracket 1. Bythis arrangement, therefore, the inner frame can swing freely about. theaxis 'of the drive-shaft without coming in contact with the shaft, whichis free to revolve under all circumstances.

In my present machine the stock-holding spindles 109, by which therotatable stock is held at one end, are made adjustable longitudinallyor in the line of the axis of suspension of the stock and rotatably in aplane at right angles thereto. The object of this adjustment is toenable the operator to accurately mount the several stock-pieces, sothat the patterns carved on them shall conform one to the other in allessential part.icularsthat is to say, both as to relative position andextent. The detailed construction of the stockholding spindle isparticularly illustrated in Figs. 30 to 33, inclusive, to whichreference is specially made in this connection.

The worm-wheel 108 of each spindle is securely mounted at the outerprojecting end of thetubular rotatable portion 150 of the spindle, thesaid tube 150 being mounted in a hollow cylindrical hearing or bushing151, carried by the outwardly-project-ing wall of the bracket 105, thetube being limited outwardly by a collar or ring 152, one face of whichbears against the inner end of the bushing, while the opposite face isadapted toliinitin its inward movement the edge of a hollow cup-shapedchuck 153, passed over the longitudinallysplit inner extension 150' ofsaid tube. Disposed about the face of the cup 153 are a series ofgripping-teeth 154, the center of the base having passed therethroughthe inner pointed stem 155 of a longitudinally-adjustable rod 156,confined within the tube 150, the pointed end or stem 155 serving toaccurately center the stock gripped by the chuck. Cpnnecting the stem155 and the rod 156 proper is a conical portion 157, whose surface issnugly embraced by the corresponding inner conical surface of the splitmembers of the extension 150, whereby as the rod 156 is driven inwardly(as subsequently to be described) the cone 157 will act as a wedge,expanding the members of the extension and forcing them into firmfrictional engagement with the walls of the chuck, thus retaining thelatter in place. The rod 156 is forced into engagement with the splitmembers of the extension 150 by the inner smooth end of anoperating-screw 158, whose screwthreaded portion is mounted at the outerend of the tube 150. By loosening the screw 158 the grip of the splitmembers or arms of the extension 150 is released from the chuck, leavingthe latter free to revolve about said extension, and thus permitting theoperator to carefully adjust all the stock of the series in the plane ofrotation of such stock, bringing the corresponding points of each pieceto be carved into accurate relation to the tools by which the carving iseffected.

Formed about the edge of the cup-shaped chuck 153 is a peripheral flange159, adapted to bear against the adjacent surface of an adjusting-plate160, which is provided with an opening to loosely pass over the collar152 and adjacent end of the chuck, the opening being sufficientlyenlarged to simultaneously pass over the inner projecting end of thebushing 151. (See Fig. 30.) Passed through suitable screw-threadedopenings formed in the plate 160 are adjusting-screws 161, the innerends of which are adapted to bear against suit-able wearing plates ordisks 162, located at the bot- .tom of suitable depressions 163, formedin the bracket 105 for their reception. By turning the screws 161. inone direct-ion it is obvious that they will force the plate outwardly,thusshifting the chuck longitudinally outwardthat is, in the line of theaxis of suspension of the stock-as seen by the dotted position of theparts in Fig. 32, it being understood, of course, that the screw 158 ispreviously unscrewed to cause the split arms of the extension 150' toloosen their grip on the chuck. By thus providing means forlongitudinally shifting within certain limits the chucks of the variousspindles stock actuated by thelatter can be adjusted longitudinally withgreater precision and nicety, enabling the operator to ma'lre the pointsof beginning for any particular design on the several stock-pieces toconform accurately one to the other. Of

course when the chuck is once gripped by the arms of the split end ofthe tubular portion of the spindles it becomes virtually a part of thelatter, so that in effect the operator by the present device adjusts thespindle both longitudinally and in a plane at right angles to the axisof suspension, said plane corresponding to the plane of rotation of thestock.
